A group of drugs closely related to ADRENALINE which act by stimulating the SYMPATHETIC NERVOUS SYSTEM. When taken by mouth they have a profound stimulating eﬀect on the brain, producing a sense of well-being and conﬁdence and seemingly increasing the capacity for mental work. They are, however, drugs of DEPENDENCE and their medical use is now strictly limited – for example, to the treatment of NARCOLEPSY.
